NTP for Windows NT / 2000 / XP / Server 2003 / Vista / Windows 7 / Server 2008
|
|
|
This NTP package contains a GUI installer for Windows which installs executable programs
which have been compiled from the original NTP sources available at the
NTP download page at ntp.org.
The GUI installer also contains the corresponding HTML based NTP documentation, plus a current
OpenSSL DLL
required by NTP to support authentication.
Unattended installation is also supported. Please see the
NTP Installer Readme
for help on how to use the installer.
Since v4.2.4p8 has been released on December 8, 2009, this version has been called "lennon"
in memoriam of John Lennon who has been shot on December 8, 1980.
IMPORTANT NOTES:
- NTP 4.2.4p8 fixes
a critical security problem.
If you are running an older version please update as soon as possible.
- This version of the installer supports PATH variables up to 8k in size, please note that older versions only support a maximum of 1024 bytes
for the contents of the PATH variable and will most probably overwrite the variable if it is longer. This will cause problems with your
Windows installation and should be avoided.
If you have any questions or feedback regarding the Meinberg Windows Installer for NTP, please send your mail to
ntp-support@meinberg.de.
